FIG. 1 illustrates an example wireless communication system 100 inaccordance with various aspects and embodiments of the subjectdisclosure. In one or more embodiments, system 100 can comprise one ormore user equipment UEs 104 and 102, which can have one or more antennapanels having vertical and horizontal elements. A UE 102 can be a mobiledevice such as a cellular phone, a smartphone, a tablet computer, awearable device, a virtual reality (VR) device, a heads-up display (HUD)device, a smart car, a machine-type communication (MTC) device, and thelike. UE 102 can also refer to any type of wireless device thatcommunicates with a radio network node in a cellular or mobilecommunication system. Examples of UE 102 are target device, device todevice (D2D) UE, machine type UE or UE capable of machine to machine(M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptopembedded equipped (LEE), laptop mounted equipment (LME), USB donglesetc. User equipment UE 102 can also comprise IOT devices thatcommunicate wirelessly. In various embodiments, system 100 is orcomprises a wireless communication network serviced by one or morewireless communication network providers. In example embodiments, a UE102 can be communicatively coupled to the wireless communication networkvia a network node 106.

The non-limiting term network node (or radio network node) is usedherein to refer to any type of network node serving a UE 102 and UE 104and/or connected to other network node, network element, or anothernetwork node from which the UE 102 or 104 can receive a radio signal.Network nodes can also have multiple antennas for performing varioustransmission operations (e.g., MIMO operations). A network node can havea cabinet and other protected enclosures, an antenna mast, and actualantennas. Network nodes can serve several cells, also called sectors,depending on the configuration and type of antenna. Examples of networknodes (e.g., network node 106) can comprise but are not limited to:NodeB devices, base station (BS) devices, access point (AP) devices, andradio access network (RAN) devices.

Turning now to FIG. 2, illustrated is an example block diagram 200showing a rateless fountain code encoding a packet in accordance withvarious aspects and embodiments of the subject disclosure.

A rateless fountain code can be a class of erasure codes with theproperty that a potentially limitless sequence of encoding symbols canbe generated from a given set of source symbols such that the originalsource symbols can ideally be recovered from any subset of the encodingsymbols of size equal to or only slightly larger than the number ofsource symbols. The term fountain or rateless refers to the fact thatthese codes do not exhibit a fixed code rate. In an embodiment, ratelessfountain codes can generate any number of encoded symbols from a givenblock of k source symbols (hence, rateless). Then it is possible todecode the encoded symbols using any n transmitted symbols, where n>k(overhead rate=(n−k)/k).

In the embodiment shown in FIG. 2, a packet 202 can be encoded with arateless fountain code resulting in three encoded packets, 204, 206, and208. Each of the encoded packets 204, 206, and 208 can comprise a set ofsource bits (e.g., 210, 214, and 218) and a set of repair bits 212, 216,and 220. The source bits comprise the information from the packet 202,and the repair bits can be used to reconstruct the packet 202 at areceiver in case any of the encoded packets 204, 206, and 208 arecorrupted or otherwise missing at the receiver.

As an example, source packet 202 can be 240 bits long and can betransmitted to a UE that has a 3 way multi-connectivity split bearerestablished with the NR network. Based on these 240 source bits, arateless fountain code is used to generate 240 repair bits. The 240repair bits are combined with 240 source bits to create, for example, 3PDCP packets (e.g., encoded packets 204, 206, and 208) of size 160 bitseach, where each PDCP packet contains 80 source bits and 80 repair bits(e.g., encoded packet 204 comprises 80 source bits in section 210, and80 repair bits in section 212). So, a total of 480 bits are transmittedfor the 240 bit URLLC packet. Based on the properties of the ratelessfountain code, the decoder at the UE PDCP layer can reconstruct thepacket 202 as long as any 320 bits are received successfully. This meansthe UE needs to successfully receive only 2 out of 3 transmitted packetsin order to decode the URLLC packet successfully.

In the above example, since 480 bits are transmitted for a 240 bit URLLCpacket, the overhead to achieve this additional reliability enhancementfor URLLC is (480−240)/240=100%. If we compare this to a traditionalpacket duplication solution where the same URLLC packet is duplicatedand transmitted over the 3 multi-connectivity legs, the total number oftransmitted bits are 240×3=720 bits. So, the overhead for thetraditional packet duplication case is (720−240)/240=200%. This meansthat the proposed solution described in this paper has the potential toprovide the same level of reliability enhancement as a packetduplication solution with about half the bandwidth overhead.

It is to be appreciated that in other embodiments, the size of thepacket 202 can be different, and the size and number of encoded packetscan also be different. In at least one embodiment, the number of encodedpackets (e.g., packets 204, 206, and 208) that are generated due to therateless fountain code can be based on the number of network paths ofthe split bearer, or the number of relay devices that the transmittertransmits the encoded packets through to get to the receiver. In anembodiment, the rateless fountain code can be a Raptor code. In anotherembodiment, the modified PDCP technique of using the rateless fountaincode can be performed on any packet on a bearer that satisfies apredetermined criterion relating to latency and reliability. As anexample, there may be bearers other than URLLC type bearers that requirehigh reliability and/or low latency. These techniques disclosed hereincan also be applied to such bearers.

Turning now to FIG. 3, illustrated is an example block diagram 300showing a multi-connectivity split bearer in a radio access network inaccordance with various aspects and embodiments of the subjectdisclosure.

In the embodiment, the radio access network can be a traditional radioaccess network, or can be a Cloud Radio Access Network where some of theprocessing layers of the radio access network are performed in thecloud, allowing for smaller and more distributed transmitters (e.g.,308, 310, and 312). In other embodiments, the radio access network canhave a functional split, where some of the functions are performed atCentral Unit (CU) 302, and other functions performed at a DistributedUnit (DU) (e.g., 308, 310, and 312). In this architecture, CU and DU canbe defined as follows.

A CU can be a logical node that includes the gNB functions like Transferof user data, Mobility control, Radio access network sharing,Positioning, Session Management etc., except those functions allocatedexclusively to the DU. CU controls the operation of DUs over front-haul(Fs) interface. A central unit (CU) may also be known as BBU/REC/RCC/C-RAN/V-RAN.

A DU can be a logical node that includes a subset of the gNB functions,depending on the functional split option. Its operation is controlled bythe CU. Distributed Unit (DU) also known with other names likeRRH/RRU/RE/RU. In an embodiment, DUs 308, 310, and 312 can be connectedvia a wireline communication or via a wireless communication with the CU302. Also, in an embodiment, DUs 308, 310, and 312 can have some layersof the RAN protocol stack (e.g., Physical Interface, Media AccessController and Radio Link Control) while the Packet Data ConvergenceProtocol (PDCP) layer 306 and the Service Data Adaptation Protocol(SDAP) layer 304 and other layers can be a part of the CU 302.

In an embodiment, the rateless fountain code can be applied to thepackets at the PDCP layer 306 or above the PDCP layer 306 (e.g., at theSDAP 304). After the rateless fountain code is applied to a packet agroup of encoded packets can be formed with each containing a portion ofthe information bits of the original packet. Each respective encodedpacket can be transmitted to the UE 314 via respective relay devices(DUs 308, 310, or 312) at the same time. The UE 314 can receive theencoded packets and use a rateless fountain decoder to decode theencoded packets to reconstruct the original packet. Even if one of thetransmissions from DUs 308, 310 or 312 are corrupted, as long as enoughpackets are received that are at least the same size as the originalpacket, the original packet can be reconstructed.

It is to be appreciated that in other embodiments, there can be more orfewer DU devices. The number of the DU devices can depend themulti-connectivity capacity of the UE 314 or the RAN, as well as thenumber of DU devices within range of the UE 314. In an embodiment, thenumber encoded packets generated by the rateless fountain code can bebased on the number of paths, or DUs available for the split bearertransmission.

In an embodiment, the advantages provided by this technique of ratelessfountain codes and multiconnectivity can significantly increase thereliability of URLLC services compared to earlier releases. Thedisclosed technique can also provide such increase in reliability withmuch less increase in bandwidth need compared to other state-of-the-artsolutions such as packet duplication. Furthermore, this technique isbased on enhancements made to the NR air interface protocol stack, andspecifically at the PDCP layer rather than at the application layer forprior state-of-the-art solutions. Hence, this solution is closer to theRAN air interface, which makes it more suitable for a tight latencysensitive service such as URLLC.

Turning now to FIG. 4, illustrated is an example block diagram 400 of atransmitter's packet data convergence protocol layer 402 in accordancewith various aspects and embodiments of the subject disclosure. Thetransmitter's PDCP layer 402 can be part of a radio access network(e.g., for a downlink communication) or part of a UE's protocol stack(e.g., for an uplink communication).

In an embodiment, the PDCP layer 402 depicted here can be part of a CUor gNB, or C-RAN environment where the PDCP functions are performed.

In an embodiment, when a URLLC bearer is established, an N-way splitbearer connection with modified packet duplication (using the ratelessfountain code technique described herein) is set up between the RAN andthe UE using multiconnectivity. A URLLC packet arrives at thetransmission buffer sequence numbering function 404 as a PDCP servicedata unit (SDU). The PDCP layer 402 processes the PDCP SDU as normal upto the header compression function 406 where the PDCP layer 402recognizes the URLLC SDU packet as belonging to a split bearer soforwards the packet 418 to the modified packet duplication function 408which is executed before the integrity protection 410, ciphering andPDCP header addition function 412. The modified packet duplicationfunction 408 executes the encoder processing for a pre-configuredrateless fountain code to generate N PDCP Protocol Data Units (PDUs)that are generated for transmission corresponding to the N-way splitbearer connection. Integrity protection and ciphering processing can beexecuted for the N PDCP PDUs at the Integrity Protection function 410,and then PDCP header function 412 can add identical PDCP headers to eachof the N PDCP PDUs since this is a split bearer with packet duplication.The N PDCP PDUs are transmitted via N network routes to the UE by therouting function 414.

The PDCP layer 402 can recognize the packets that are associated withthe URLLC bearer (e.g., 418) and forward those to the modified packetduplication function 408 while other packets (e.g., 416) are forwardedto the PDCP header function 412.

Turning now to FIG. 5, illustrated is an example block diagram 500 of areceiver's packet data convergence protocol layer 502 in accordance withvarious aspects and embodiments of the subject disclosure.

At the receiving PDCP layer (e.g., for a downlink communication to a UE,or for an uplink transmission to a network). The encoded packets can bereceived at the PDCP Header removal function 504 where the headers areremoved, and then deciphering layer 506 and integrity verification layer508 can decipher and verify the packets.

After successfully passing deciphering and integrity verification, atthe reception buffer stage 510, the function that performs duplicatediscarding recognizes that this is a URLLC bearer, so rather thanexecuting the normal duplicate discarding function, it gathers all thereceived ‘duplicate’ packets received from lower RLC layers, it executesthe decoder for the pre-configured rateless fountain code. This modifiedduplicate discarding function needs to successfully receive only N-M ofthe transmitted PDCP packets to be able to successfully decode the PDCPPDU corresponding to the URLLC packet. As long as there are at least asmany bits in the successfully verified packets as there are in theoriginal packet, the preconfigured rateless fountain code will besuccessful in decoding the encoded packets. Then the reception bufferreordering function can pass the PDCP PDU 516 to the headerdecompression function 512.

After successful decoding of the received PDCP PDU, it is stored in thePDCP reception buffer according to its sequence number (this is normalPDCP processing). The PDCP header removal function 504 can pass the nonURLLC related packets 514 to the header decompression function 512.

FIG. 9 presents an example embodiment 900 of a mobile network platform910 that can implement and exploit one or more aspects of the disclosedsubject matter described herein. Generally, wireless network platform910 can include components, e.g., nodes, gateways, interfaces, servers,or disparate platforms, that facilitate both packet-switched (PS) (e.g.,internet protocol (IP), frame relay, asynchronous transfer mode (ATM)and circuit-switched (CS) traffic (e.g., voice and data), as well ascontrol generation for networked wireless telecommunication. As anon-limiting example, wireless network platform 910 can be included intelecommunications carrier networks, and can be considered carrier-sidecomponents as discussed elsewhere herein. Mobile network platform 910includes CS gateway node(s) 912 which can interface CS traffic receivedfrom legacy networks like telephony network(s) 940 (e.g., publicswitched telephone network (PSTN), or public land mobile network (PLMN))or a signaling system #7 (SS7) network 960. Circuit switched gatewaynode(s) 912 can authorize and authenticate traffic (e.g., voice) arisingfrom such networks. Additionally, CS gateway node(s) 912 can accessmobility, or roaming, data generated through SS7 network 960; forinstance, mobility data stored in a visited location register (VLR),which can reside in memory 930. Moreover, CS gateway node(s) 912interfaces CS-based traffic and signaling and PS gateway node(s) 918. Asan example, in a 3GPP UMTS network, CS gateway node(s) 912 can berealized at least in part in gateway GPRS support node(s) (GGSN). Itshould be appreciated that functionality and specific operation of CSgateway node(s) 912, PS gateway node(s) 918, and serving node(s) 916, isprovided and dictated by radio technology(ies) utilized by mobilenetwork platform 910 for telecommunication.

It is to be noted thatfor technology resource(s) 917 that rely primarily on CS communication,server node(s) can deliver traffic without reliance on PS gatewaynode(s) 918; for example, server node(s) can embody at least in part amobile switching center. As an example, in a 3GPP UMTS network, servingnode(s) 916 can be embodied in serving GPRS support node(s) (SGSN).

For radio technologies that exploit packetized communication, server(s)914 in wireless network platform 910 can execute numerous applicationsthat can generate multiple disparate packetized data streams or flows,and manage (e.g., schedule, queue, format . . . ) such flows. Suchapplication(s) can include add-on features to standard services (forexample, provisioning, billing, customer support . . . ) provided bywireless network platform 910. Data streams (e.g., content(s) that arepart of a voice call or data session) can be conveyed to PS gatewaynode(s) 918 for authorization/authentication and initiation of a datasession, and to serving node(s) 916 for communication thereafter. Inaddition to application server, server(s) 914 can include utilityserver(s), a utility server can include a provisioning server, anoperations and maintenance server, a security server that can implementat least in part a certificate authority and firewalls as well as othersecurity mechanisms, and the like.

Further, terms like “user equipment,” “user device,” “mobile device,”“mobile,” station,” “access terminal,” “terminal,” “handset,” andsimilar terminology, generally refer to a wireless device utilized by asubscriber or user of a wireless communication network or service toreceive or convey data, control, voice, video, sound, gaming, orsubstantially any data-stream or signaling-stream. The foregoing termsare utilized interchangeably in the subject specification and relateddrawings. Likewise, the terms “access point,” “node B,” “base station,”“evolved Node B,” “cell,” “cell site,” and the like, can be utilizedinterchangeably in the subject application, and refer to a wirelessnetwork component or appliance that serves and receives data, control,voice, video, sound, gaming, or substantially any data-stream orsignaling-stream from a set of subscriber stations. Data and signalingstreams can be packetized or frame-based flows. It is noted that in thesubject specification and drawings, context or explicit distinctionprovides differentiation with respect to access points or base stationsthat serve and receive data from a mobile device in an outdoorenvironment, and access points or base stations that operate in aconfined, primarily indoor environment overlaid in an outdoor coveragearea. Data and signaling streams can be packetized or frame-based flows.

Furthermore, the terms “user,” “subscriber,” “customer,” “consumer,” andthe like are employed interchangeably throughout the subjectspecification, unless context warrants particular distinction(s) amongthe terms. It should be appreciated that such terms can refer to humanentities, associated devices, or automated components supported throughartificial intelligence (e.g., a capacity to make inference based oncomplex mathematical formalisms) which can provide simulated vision,sound recognition and so forth. In addition, the terms “wirelessnetwork” and “network” are used interchangeable in the subjectapplication, when context wherein the term is utilized warrantsdistinction for clarity purposes such distinction is made explicit.

Moreover, the word “exemplary” is used herein to mean serving as anexample, instance, or illustration. Any aspect or design describedherein as “exemplary” is not necessarily to be construed as preferred oradvantageous over other aspects or designs. Rather, use of the wordexemplary is intended to present concepts in a concrete fashion. As usedin this application, the term “or” is intended to mean an inclusive “or”rather than an exclusive “or”. That is, unless specified otherwise, orclear from context, “X employs A or B” is intended to mean any of thenatural inclusive permutations. That is, if X employs A; X employs B; orX employs both A and B, then “X employs A or B” is satisfied under anyof the foregoing instances. In addition, the articles “a” and “an” asused in this application and the appended claims should generally beconstrued to mean “one or more” unless specified otherwise or clear fromcontext to be directed to a singular form.

In addition, while a particular feature may have been disclosed withrespect to only one of several implementations, such feature may becombined with one or more other features of the other implementations asmay be desired and advantageous for any given or particular application.Furthermore, to the extent that the terms “includes” and “including” andvariants thereof are used in either the detailed description or theclaims, these terms are intended to be inclusive in a manner similar tothe term “comprising.”
